4.4 Mounting
The Hull Unit should normally be oriented with the
hoisting/lowering motor pointing aft. If this orientation makes
the Motor Control Unit attached to the Hull Unit difficult to
access, the Hull Unit may be oriented in the most suitable
position.
Note:
The Motor Control Unit must never be disconnected from the
Hull Unit.
